Althea Lake

Overview

Althea Lake is a 43-acre warm-water lake in Tyngsborough that drains north into Mascuppic Lake. Much of its shoreline is marsh, so development is limited to part of the south shore.

Fishing

Limited reports suggest a good largemouth bass population with the occasional larger fish, and access limits likely keep fishing pressure low. Althea has produced award-size largemouth bass.

Species

Species found in MassWildlife surveys: largemouth bass, chain pickerel, yellow perch, white perch, black crappie, bluegill, pumpkinseed, brown bullhead, golden shiner.
